ARTIFICIAL FUEL.

Application filed October 3, 1923. Serial No. 666,401.

To all whom it may concern Be it known that I, SHULEM J. MAR- GHOSKY, a subject of the King of Rumania,

residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Artificial Fuel, of which the following is a specification.

My present invention relates generally to artificial fuel and more particularly to what are commonly known as briquets, my primary object being the provision of an artificial fuel of this nature which will be slow burning and will produce an intense heat, and which will be quick and easy to start.

WVith these objects in mind my invention further proposes an artificial fuel which may be made for the most part from more or less waste materials, as well as a briquet having a core or body and a core covering which are slightly varied as to their constituents so that while quick to catch its main portion will be slow burning and in this way adapted to develop maximum heat.

In the accompanying drawing illustrating my present invention and forming a part of this specification,

Figure l is a perspective view of a briquet formed according to my invention, and

Figure 2 is a sectional view taken diametrically therethrough.

According to my invention I propose a briquet A pressed to any suitable form such for instance as shown in Figure l by heavy pressure in any suitable mold or die and having its core or main. body portion B formed of a mixture of pulped wood, pulped paper, tar, crude oil and pulped cocoanut skins.

Of these materials any suitable wood may be utilized, including that which is not useful for other purposes. The paper also may be waste paper of any suitable character for instance waste newspapers without the necessity of de-inking or otherwise prelimi: narily treating the same. Tar and crude oil may be the ordinary commercial products and the cocoanut skins I have in mind are those portions of the cocoanut around the inner white meat, containing considerable oil in addition to the other woody fibers which burn slowly and with intense heat especially in conjunction with the pulped wood and paper.

After these materials are thoroughl mixed either by machinery or by han they are preferably kneaded and then placed in forms or molds and subjected to any pressure, being first however roughly shaped and surrounded by a layer C of material containing much the same ingredients except that the pulped paper is omitted as well as the pulped wood and finely comminuted wood such as sawdust in a medium fine state is substituted. This sawdust when mixed with the tar, crude oil and cocoanut skins forms an outside layer 0 for the briquet adapting it to ignite quickly and easily and in this way readily induce combustion of its core or body portion.

As to the core or body portion B the ingredients are preferably utilized in about the following proportions: pulped wood from twenty to twenty-five per cent; pulped paper from twenty to twenty-five per cent; tar ten per cent; crude oil about thirty-five per cent and pulped cocoanut skins from five to ten per cent. In addition to these, the main ingredients, I have found it desirable in dry climates to use about five per cent of magnesite and in wet climates about five per cent magnesite with an additional amount of magnesium chloride about five per cent.

The artificial fuel as thus constituted and preparedaccording to my invention is slow burning as a whole, develops an intense heat and yet in view of its covering or outer layer pulpecl paper, tar, crude oil and cocoanut skins, and having a covering around the core formed of a mixture of finely comminuted 10 Wood, tar, crude oil and coeoanut skins.

In testimony whereof I have afiixed my signature.
